CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is the U.S. national phase of PCT Application No. PCT/CN2018/124251 filed on Dec. 27, 2018, which claims a priority to Chinese Patent Application No. 201810018031.8 filed in China on Jan. 9, 2018, the disclosures of which are incorporated herein by reference in their entireties

TECHNICAL FIELD

The embodiments of the present disclosure relate to the field of communication technologies, and in particular, to a method and device for measurement reporting.

BACKGROUND

With development of mobile communication technology, more and more technologies have been introduced to improve communication efficiency. For example, a mechanism of Long Term Evolution (LTE) Automatic Neighbor Relation (ANR) is introduced: in order to perform handover and interference coordination, an evolved Node B (eNB) needs to establish and maintain a neighbor relation table for its cells. A function of automatic neighbor relation is used to assist the eNB to discover unconfigured neighbor cells and trigger establishment and maintenance operations of corresponding entries in the neighbor relation table. The mechanism of the automatic neighbor relation is not only suitable for discovering neighbor cells of a same frequency, but also used for discovering neighbor cells of different frequencies and neighbor cells of different systems. A process of neighbor cell discovery is shown in FIG. 1 .

In FIG. 1 , a User Equipment (UE) within coverage of an eNB A completes conventional measurement of neighbor cells and reports measurement results. In a measurement report, a combination of a frequency and a Physical Cell Identifier (PCI) of a cell B is used as an identifier of the measured cell (step 11). The eNB A finds that the frequency and the PCI carried in the measurement report correspond to an unconfigured neighbor cell, then instructs the UE to read broadcast information of the cell corresponding to the combination of the frequency and the PCI, so as to obtain parameters of the cell B, such as Cell Global Identifier (CGI), Tracking Area Code (TAC) and Public Land Mobile Network (PLMN) identifier. The instruction command is issued to the UE in a form of a measurement configuration, and is associated with a measurement identification (ID) (step 12). After obtaining the above measurement configuration, the UE starts a timer and starts a system information acquisition process of a target cell (step 13); if the UE obtains the required system information before the timer expires, it reports to the network the above measurement ID and the information of the cell B, such as the PCI, the TAC, the CGI, the PLMN (step 14); if the UE has not obtained all the required system information when the timer expires, the UE reports the above measurement ID to the network. Because the required system information is not included in the reported content, the eNB A can infer that the UE failed to obtain the required information of the neighbor cell. If the UE successfully obtains and feeds back the required information, the eNB A can add the cell B to a neighbor relation table of a cell A. In the figure, parameters corresponding of the eNB A include: Cell A, Freq=M, PCI=N, GCI=O, and parameters corresponding to the eNB B include: Cell B, Freq=X, PCI=Y, GCI=Z.

Compared with traditional manual configuration process of neighbor relation, the mechanism of the automatic neighbor relation not only avoids calculation of engineering parameters during a planning stage and path test assistance during a optimization stage, but also reduces occurrence of missing of matching and mismatching in the neighbor cells, and it improves optimization efficiency while reducing costs.

When the mechanism of LTE ANR is used for New Radio (NR), the following problem will occur: if the UE finds that an NR cell does not broadcast Remaining Minimum System Information (RMSI) after reading system information of the NR (for example, Master Information Block (MIB) does not contain acquisition auxiliary information of the RMSI or indicates that the RMSI is not broadcast), the UE cannot report until the timer expires. Based on the reporting of the UE, a serving base station of the UE cannot know that a failure to read the system information of the target cell is caused by that the target cell does not broadcast, resulting that the serving base station might configure another UE to continue to measure the target cell.

DETAILED DESCRIPTION

Technical solutions in the embodiments of the present disclosure will be described clearly and completely below in combination with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments merely relate to a part of, rather than all of, the embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by a person skilled in the art without creative efforts also fall within the protection scope of the present disclosure.

The term “include” and any variants thereof in the specification and the claims of this application are intended to cover non-exclusive inclusions, for example, processes, methods, systems, products, or devices that include a series of steps or units need not be limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to these processes, methods, products, or devices. In addition, the term “and/or” that used in the specification and the claims indicates at least one of associated objects; for example, A and/or B indicates individual A, individual B, or A and B.

In the embodiments of the present disclosure, such word as “exemplary” or “for example” is used as an example, illustration, or description. Any embodiment or design described as “exemplary” or “for example” in the embodiments of the present disclosure should not be construed as more preferred or advantageous over other embodiments or designs. Specifically, use of words such as “exemplary” or “for example” is intended to present related concepts in a concrete manner.

In order to better illustrate the technical solutions of the embodiments of the present disclosure, a process of system information transmission of a New Radio (NR) system is discussed in the following.

In the NR system, the system information includes Minimum System Information (MSI) and other System Information (other SI). The MSI is transmitted in two parts: Master Information Block (MIB) and Remaining MSI (RMSI). The RMSI is also known as System Information Block 1 (SIB1). Some or all of identification information of the cell required by ANR, such as CGI, TAC, and PLMN identifier, are broadcast in the RMSI, and the remaining part (if any) is broadcast in the other SI. Scheduling information transmitted by the other SI is indicated by the RMSI, that is, the UE must obtain the RMSI before obtaining the other SI.

The UE can search for the MIB in a set of preset frequency locations, and once the MIB is found, transmission parameters of the RMSI, such as frequency location, can be determined according to indications of the MIB. That is, the UE must obtain the MIB before obtaining the RMSI.

However, in certain network configurations, the MIB does not indicate the transmission parameters of the RMSI:

Case 1: a current NR cell does not work independently, and it does not need to broadcast the RMSI;

Case 2: the current NR cell has a wide bandwidth and contains multiple frequencies of a set of preset frequency locations. It indicates the transmission parameters of the RMSI on the MIB transmitted at only some of the multiple frequencies (a MIB containing RMSI parameter indication information is called a first type of MIB); if there is a MIB to be transmitted at remaining frequencies, although the MIB does not indicate transmission parameters of the RMSI (a MIB that does not contain the RMSI parameter indication information is called a second type of MIB), but it can indicate transmission configuration information of the first type of MIB, such as transmission frequency location information, as shown in FIG. 2 .

The embodiments of the present disclosure will be described below in combination with the accompanying drawings. The measurement reporting method and device provided by the embodiments of the present disclosure can solve a problem that: after the UE reads the system information of the NR cell, if the NR cell does not broadcast the RMSI, the UE must wait for expiring of a timer before reporting. Therefore, in the embodiments of the present disclosure, the timer is started according to a measurement configuration of a target cell transmitted by the network side, and when it is determined that the identification information of the target cell cannot be obtained, it is reported to the network side that the UE cannot obtain the identification information of the target cell, so as to avoid that the UE needs to wait for expiring of the timer before triggering report, and the ANR measurement process of the UE is accelerated.

The measurement reporting method and device can be applied to a wireless communication system. The wireless communication system may be a 5th Generation (5G) mobile communication system (referred to as a 5G system for short hereinafter). Referring to FIG. 3 , a schematic structural diagram of a wireless communication system according to an embodiment of the present disclosure is provided. As shown in FIG. 3 , the wireless communication system may include a network-side device 30 and a UE. For example, the UE may be referred to as a UE 31, and the UE 31 may communicate with the network-side device 30. In a practical application, a connection between the above devices may be a wireless connection. In order to conveniently and intuitively represent a connection relationship between various devices, a solid line is used in FIG. 3 for illustration.

It should be noted that the above wireless communication system may include a plurality of UEs, and a network-side device may communicate with the plurality of UEs by transmitting signaling or transmitting data.

Obviously, the described embodiments merely relate to a part of, rather than all of, the embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by a person skilled in the art without creative efforts also fall within the protection scope of the present disclosure.

Referring to FIG. 4 , a flowchart of the measurement reporting method according to an embodiment of the present disclosure is provided. The method may be executed by the UE, and the specific steps are as follows.

Step 401: starting a timer according to a measurement configuration of a target cell transmitted by a network side.

Optionally, the timer may be configured by a network side or predefined in a protocol.

Step 402: before the timer expires, determining that identification information of the target cell cannot be obtained.

Optionally, in step 402, before the timer expires, information of an MIB of the target cell is obtained according to the measurement configuration; and when the information of the MIB carries a first indication indicating that the target cell does not broadcast RMSI, it is determined that the identification information of the target cell cannot be obtained.

Optionally, the first indication is represented by one or several predetermined code points or a combination of the predetermined code points, wherein the one or more predetermined code points are carried by one field in the information of the MIB, and the combination of the predetermined code points is carried by multiple fields in the information of the MIB.

Step 403: reporting to the network side that the identification information of the target cell cannot be obtained by the UE.

Optionally, in step 403, the timer is stopped before the timer expires; and it is reported to the network side that the identification information of the target cell cannot be obtained by the UE.

Optionally, in step 403, the timer is stopped before the timer expires; and it is explicitly or implicitly reported to the network side that the identification information of the target cell cannot be obtained by the UE. For example, the way of explicit reporting is as follows: transmitting second indication information to the network side, wherein the second indication information indicates that the target cell does not broadcast the identification information of the cell or RMSI.

In this way, it is unnecessary for the UE to wait for expiring of the timer before triggering to report, and an ANR measurement process of the UE is accelerated.

Referring to FIG. 5 , a flowchart of the measurement reporting method according to an embodiment of the present disclosure is provided. The method may be executed by the UE, and the specific steps are as follows.

Step 501: starting a timer according to a measurement configuration of a target cell transmitted by a network side.

Step 503: transmitting to the network side the system information required by the target cell and a transmission frequency of an MIB, wherein the MIB is an MIB of transmission location information of RMSI, and the transmission location information of the RMSI is actually read by the UE.

Optionally, in step 503, the timer is stopped; and the system information required by the target cell and the transmission frequency of the MIB is transmitted to the network side.

In this way, it is unnecessary for the UE to wait for expiring of the timer before triggering to report, and an ANR measurement process of the UE is accelerated.

Example 1: a scenario in which the RMSI is not broadcast over the network is provided.

Referring to FIG. 6 , a flowchart of a measurement reporting method according to an embodiment of the present disclosure is provided. The specific steps are as follows.

Step 602: after receiving the measurement configuration by the UE, starting, by the UE, a timer;

Optionally, a timing length of the timer may be configured by the network side or agreed by the protocol.

Step 603: before the timer expires, obtaining, by the UE, the information of the MIB of the target cell corresponding to the measurement configuration, wherein the information of the MIB carries an indication that the cell does not broadcast the RMSI.

Step 604: stopping, by the UE, the timer, and reporting, by the UE, to the network side that the UE has not obtained the identification information of the corresponding target cell.

Optionally, the UE reports to the network side explicitly or implicitly that the identification information of the corresponding target cell is not obtained by the UE.

1) Content of the explicit report includes any one or more of the following: that the measurement ID=X, that ID indication of the target cell is not obtained, and that the target cell does not broadcast the RMSI indication, etc.;

After receiving the reported content, the network side can infer that the UE failed to read the identification information of the target cell.

In this way, it is unnecessary for the UE to wait for expiring of the timer before triggering to report, and an ANR measurement process of the UE is accelerated.

Example 2: a scenario in which the RMSI is broadcast over the network is provided.

Referring to FIG. 7 , a flowchart of a measurement reporting method according to an embodiment of the present disclosure is provided. The specific steps are as follows.
